Stereo Audio Amplifier 5W Circuit
TEA 2025 Circuit 3D view
Stereo Audio Amplifier:
Amplifiers are widely used to increase the input power of any circuit. It is very important to use amplifier to amplify any audio signal as it is impossible to amplify the audio signal without amplifier. Amplifier refers to any circuit that amplifies the power signal.
In today's article we are going to show you how you can easily make a (5 watt) stereo audio amplifier circuit with the help of (TEA2025)Silk Screen Component view
Stereo Audio Amplifier:
A 16-pin IC. This is an IC used in a mini audio amplifier circuit. It is originally designed for portable cassette players and radios, but can be used for MP3, mini-woofer, or any audio output - a pretty decent stereo audio for iPod or player. Can be used to make amplifiers.

Stereo Audio Amplifier:
It uses 9 volts, the positive point of which is given on IC PIN No. 16 - Audio from IC PIN 7 and 10 which is amplified by this circuit and out of IC PIN 2 and 15. We can hear it with the help of speakers. Volume is not used in this circuit. You can control the tone of audio by inserting volume on the audio input.
